What is green coffee?
Green coffee is the seed of the coffee fruit after harvesting, processing and drying, but before roasting. Its colour can range through green, blue-green and yellowish tones, and it does not yet have the roasted aroma we recognise when opening a bag. It is not a separate variety or a particular drink: it is the state in which coffee travels and reaches the roaster.
What the bean already carries
That seed contains the results of place, variety, cherry ripeness, cultivation, harvesting and the producer's work. It also carries the imprint of washed, natural or honey processing and of the drying stage. Roasting can develop these attributes and make them soluble, but it cannot create from nothing a quality that was absent from the green coffee.
Quality, moisture and storage
Before buying or roasting, physical and sensory qualities are examined: uniformity, defects, aroma, density, moisture and performance in a small roasted sample. Green coffee needs a stable, clean environment free from strong odours. Excess heat or humidity and sudden changes can accelerate ageing. Careful storage is part of protecting the work already completed at origin.
From green coffee to a roast profile
Every lot responds differently to heat. Density, size, moisture and process guide the roaster, who builds a profile to develop sweetness, aroma, acidity and body without erasing the coffee's character. Light, medium or dark is not merely a colour: it reflects time, energy and decisions. The same green coffee can therefore express itself in different ways once roasted.
Why it matters when we drink a cup
Although we normally see only the brown roasted bean, understanding green coffee changes the way we taste it. Quality does not begin at the machine or with the recipe; it begins much earlier. Reading origin, variety and process on a label is not about collecting data. It brings us closer to the decisions and people who made that cup possible.
A living material that changes over time
Green coffee does not remain identical forever. Even under good storage it evolves and may lose intensity, freshness or definition. Traceability, harvest information when available and buying quantities suited to the roasting rhythm therefore matter. Caring for a lot also means not leaving it still for too long: roast it at the right moment and keep observing how it responds as the season moves forward. Freshness is part of the story, not a separate detail.
